Correlation matrices relating site factors to ACD, including elevation a.s.l. (Elev in m), fraction of photosynthetic vegetation as determined by CLASlite (PV), slope (degrees), REM (elevation above nearest drainage), fraction of soil cover as determined by CLASlite, and aspect for the (A) northern region and (B) southern region. The scatter plots display the following information: blue points indicate individual pixel values, open circles represent the median value within each of ten bins evenly spaced along the horizontal axis (these are intended to assist in visualization and do not impact model fit), lines are the best fit polynomials for the data being compared. In the lower left portion of the matrix are the r2 values for the best-fit polynomials; *** indicates statistical significance of P < 0.001.
